Application .fl led April 28,

This invention relates to. locking devices and in particular tonne adaptedifor use in" connection with automobile license plates andlicense plate holders.

A particular object of' the-invention is, to, provide; a locking device which. can. be readily. manipulated. to lock a. plurality. of" members together so that-when theyfare sub- I ening during constant jarring,. such as is present inlve-hicle license. plates and plate holders.

A'still further objector theinvention is to. provide a simplified. locking device which.

may bejsold at smallicost and which is ef fective to; securely lock together a. plurality of members so that no amount. ofijolting' or jarring will, cause the. locking member to become, accidentally misplaced, resulting in. a loss ofv one ofthe members,

To enable others'skilld'in the art to fully comprehendthd underlying features of my invention that they may embody the same in the various modifications in structure and relation contemplated, a drawing depicting a preferred form has been annexed as a part of this disclosure and in such drawing, similar reference characters denote I corresponding-parts throughout all the "iews, of which,

Figure 1 is a front View in elevation of a license plate and license plate holder connected together with my improved locking device.

Figure 2 is an enlarged sectional View taken'on the line 2-2 of Figure 1 showing the position of my locking device when the same is inserted in position to hold a license plate in connection with a license plate holder.

Figure 3 is a view in perspective of the license plate, license plate holder, resilient washer and lock washer, all as'theywould appear if separated preparatory toassembling to receive the locking member.

Referring to the. drawings in detail 5 indicates a license platev and 6 a license plate 1927. seriainmismsa.

holder and the. license. plate securely. togethe er, Ij'makeuse. offa rubber washer 7 of. sufiie cient- 'thicknessto form a resilient padf member between thelock washer. 8 andithe license. plate holder 6, the rubber. washer? being, providediwith,anielongated. s]ot.9 which is. ar-ranged'to.match the. slot=lilie opening; 10. in the license plate holder. 6,.a.suitable slot 11;

being also provided in. the upper. corner? of the license plate to .match with the slot" 10. of

the license plate holder. 6. and.the.slot 9 of.

the. rubber washer 7.. Reference is made to arubber washer. infthis. instance but itis. of course.understood that. this .washer may be.

made. of. any resilient. substance, [such rubberizedleather. or. fltwvhichQwill: act. as a.

filler between thelock washer 8 and the,li-. censeplate holder. 6,-andreferring to the :lock

washer 8,-Iit, will be. noted that. the. same is. provided. with a. horizontally extending slot: 12 T which is 3 formed by punching out of the:

material ofthe lock washer, the positioning tongues 13 which project forwardly from the surface of the locking washer 8 and are adapted to pass through the slot 9 of the rubber washer 7 and have their ends positioned in the slot 10 of the license plate holding plate 6. These positioning tongues prevent rotation at the lock washer-"8 when the winged locking device or member 14: is passed through the slots 9, 10, 11 and 12and revolved to position as shown in Figure 1 and'Figure 2 so that its winged portions 15 are in vertical position and rest in the locking depressions 16 formed on the outer face of the lock washer. 8, these locking depressions being somewhat semi-conical and opening from the slot 12. It will be evident that the arcuate shaped underside of the wings 15 are adapted to snap into these depressions 16 and the rubber washer having been compressed during the revolving movement of the locking member, will expand and cause the locking member 14 to be securely seated in the depressions 16.

These cam surfaces of the locking memholder or may be used to bind any number of members together to which it may be adapted, it ot course being understood that the shank portion 17 of the winged locking member may be lengthened to accommodate any number of parts to be joined together and the locking member may be made of any suitable size to carry out the work For which it is designed, it being understood that the cam surfaces of the wings 15 will etlectively force together any pieces to be held in close relation and the cam surface when .once positioned in the depression 16 of the lock washer will etlectivcly hold the parts to gether and no amount oi? vibration will loosen the locking member beeause it is lirmly seated in the depression 16 and the resiliency of the rubber washer between the lock washer 8 and the piece oi metal adjoining it will always retain the washer in connection with the locking member.

It is evident, therefore, that l have provided an improved locking member which will ei'l'cctively carry out the work -for which it has been designed and which can'be made up at small cost and will not be lost or jarred loose from its holding position by vibration.

While it have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated'parts without departing from the spirit of the invention or the scope of the appended claims.

Having thus described'my invention What I claim as new and desire to secure by United States Letters Patent isr 1. The combination with a plurality of members having openings therein and arranged to be secured together, oi" a locking device comprising a locking member, a locking washer, tongues on the washer arranged to enter the opening in one of the n'ieinbers to be secured and a resilient pad interposed between said member and said washer where by the locking member Will be resiliently maintained in its locking position. 7
